What 2004 Jaguar XJ8 owners say
Suspension
The airbag light came on with only 54,000 miles on this Jaguar, that is not normal as I have owned Jaguar cars for 3 decades. Also the air suspension failure occurred at 55,000 miles which is the current mileage and the car was parked for two weeks without any movements. This vehicle drives less than 3000 miles a year now and I'm super disappointed in this factor where as my wife's Mercedes s500 with 139,000 miles on it has no issues on it at all.
